Any flow difference between PI exhaust manifold and non-PI exhaust manifold?

[5spd GT]

Just like the title says, I was just curious if there is a power difference between the two?

none

Get a set of long tubes

 

[5spd GT]

Okay, well are they different headers? Part numbers?

 

[RandyStinchcomb]

they have different part #'s but the port is the same for both, so there is NO advantage of one over the other
